Automatically delete watched videos

The request I would ask if I could, is for a feature add to delete watched TV and Movies (different options for each) during\before\after sync.
TV Options - Delete parent folder and all content (incl subdir) if no other video files remain (yes\no)
Movie Options - Delete parent folder and all content (yes\no)
Perhaps an other option if watched more than X days ago. And watched status full or partial.

At first, I saw this as a scary feature, but the thing is, I do that exact thing manually. So If an option is added to make sure nothing is accidentally deleted, the best way to implement this option would be to....

When an episode finishes, call the built-in mechanism for file deletion in Kodi, or mimic Kodi's and use Plex's mechanism. There are two screens: Remove from Library, and Delete File.
For empty folders, provide a script to recursively delete EMPTY folders.
Have both options OFF by default.

For heaven's sake, do NOT delete the videos automatically, because sometimes Kodi messes up and thinks the video is finished at the very beginning. Ask the user each time, or (even better) in bulk when they return to the Kodi menus.
